I saw this thread two weeks ago on the Deadspace forums where it actually originated, with the user complaining and one of the EA moderators brought it up with their boss, which later had the thread skyrocket in replies after they saw EA posting there.
While I approve of Viscerals actions here, I am seriously confused how someone who plays with their chin is going to play this game. There's no way they can survive the ending of the game with only their chin, as I've seen the videos how he plays. I'm sorry to say, but there's no way. Not that he shouldn't at least try and have some fun! But honestly, I just don't see why every developer for every game he's going to buy will have to tailor to his injury. Is it fair to him? Yup. Is it nice of the developers to do so? Sure as heck, yes! But is it necessary...? I don't know. Oh well, best of luck with him, but I suppose I'm just cold hearted since I don't instantly jump aboard the petition or such. :-(
